I have had this hitch for a year and it has towed trailers all over the northeast. It is still in great shape and works great.



by:

Hitch is very heavy duty which is nice. Think some more engineering could go into it so you don’t have to use the Allen to snug hitch to keep from rattling. I ended up purchasing the rubber inserts. Definitely recommend if towing heavy trailers.



by:

I have been completely satisfied with this product. Very durable, solid beyond my expectations. Whether towing 1/2 ton or 6 tons I have no concerns that the trailer and load aren't safe and secure. Would purchase again but won't need to as this hitch was built to last.



by:

First of all, ETRAILER is a great company in my opinion. Their selection, prices and customer service are all great.

This hitch is stout! I'm the type that I'd rather have more capability than what I may actually use. For what I will use this for, I'm 100% sure it will be way more than I'll ever need but I'm also confident that I would not have any issues using it regularly at it's maximum capability. The construction of it is top notch and I'd be willing to bet it can do more than what it's rated for.

I will definitely be ordering the 20K Pintle that works with this as well as a Curt 5th Wheel and Gooseneck. Thank you ETRAILER and thank you CURT for amazing service and and amazing product.



by:

What is there to say about a perfect hitch like this one? Why haven't you got it yet would be it. I have a 2015 Dodge Ram 2500 and it went low enough for any trailer I pulled. Performed perfectly at pulling any trailer, of any size, of any weight. Still use it today (2023) It does have a locking bolt if you don't like hitch ball rattle. But you don't have to use it and it works fine without it. The hitch rattle doesn't bother me. I guess the only thing I would have liked is if it had come with another drop hitch with 1 7/8 ball on one side. And maybe a hook or a hole for a clevis on the other side.



by:

Super strong, not much noise. Have it on a ram 2500 on 35” tire with stock suspension and it goes low enough for my 4x8 trailer and tall enough for my dump trailer and flatbed



by:

Great product. I bought one for myself a year ago and ordered this one for a coworker.



by:

Just what I needed for the Ram 2500, so I can pull smaller trailers and keep them level.



by:

Very well built. I've had it for one year and it's exactly what I needed. Heavy duty towing capabilities, adjustable and two ball sizes. What more could you ask for?

Supreme

10/3/2022

After one year it has held up fantastically. Very little to no rust showing. It has been very durable through the heavy snow and salt life after a winter season. I still would recommend this to anyone.



by:

Overall quality looks good . Powder coating is less than adequate 1 day in the rain it has rust on it

So sorry to hear of any inconvenience with your order. Since this product is covered by a 1-year limited warranty, I have forwarded your review to our customer service department for direct follow-up with you.



by:

I ordered the adjustable ball mount and it showed up in two days and in perfect shape. Etrailer has always delivered parts very timely. Thanks.



by:

I have dealt with these folks before, timely shipment, product received as advertised



by:

Very strong and durable hitch. Elevation and dropping is very convenient.

2 big issues with his hitch.

1) does not have an option to buy a 1 7/8 ball.
2) even with a pin lock on the hitch, the balls can still be stolen with its design. If the balls are stolen they can not be easily replaced or cheaply.

Overall, does the job, but once it is stolen, I’ll be buying something better theft protection.

As with any ball mount, it is recommended to remove it from the vehicle when it is not being used. This will protect it against theft and corrosion. Some States actually mandate that a ball mount be removed when not towing. If removing the ball mount is not feasible, a hitch lock # e98881 can be used in place of one of the pins that hold the ball in place.

Jared

3/30/2019

Hitch hasn’t been stolen. Easy hook up. Pulls 12k with ease. Rust build up is a little disappointing, but still have plenty of life in it. Hitch has saved my bumper from damage several times.



by:

The hitch arrived quickly and as expected. Normally a hitch that weighs as much as this one (37.5lbs shipped) is hard to order online due to the weight of the item but etrailer really made it easy. The interaction with the folks from etrailer was perfect. They were detailed in their email and made every effort to make this a personal experience.



by:

The product is everything they said it was and more, the adjustment capabilities are great along with the ability to extend the receiver. I plan to pull a 26 foot car trailer at about 12,000 pounds loaded. The service and concern as always was excellent. I highly recommend this product and certainly etrailer.



by:

Always a pleasure doing business with etrailer. Product came with free shipping in 3 days! What more could you ask for?



by:

Fast shipping from etrailer. Very heavy duty unit and perfect for my 2020 Silverado 2500HD. I needed an adjustable drop hitch and this unit works perfectly between different trailers that I tow.

Ron

12/17/2021

Had the hitch a year and still love it. When not in use I remove the hitch from receiver and store it away for fear of theft.



by:

This is the quickest and easiest ball mount I have ever seen or used. Just by pulling 2 pins you can easily adjust the ball height and size in seconds. Very pleased with Curt product. Etrailer.com has great products and great service.



by:

Strong as on ox. Love it. Very easy to adjust and flip. The real deal!

Teamtrailrat

9/4/2023

This dude is the beast! Strong as an ox. Tremendous vertical range by flipping vertically. Appreciate rubber bushings on back of the 2 ball mount that absorb shock against the gusset. I tow 3 types trailers all different heights. Adjusts quick n easy. Love it.



by:

The shank has a lot of play , up down .. side to side
Slops around while towing
When you brake the ball will shift up and down causing it to be uncomfortable

Etrailer Expert

I do have a solution for you. I recommend adding an anti-rattle device such as part # BX88312 to help take out movement in the hitch receiver.



by:

Very well made and heavy duty.



by:

Heavy, simple, solid. The clever anti-rattle feature is nice too; Great ball mount!



by:

Easy to adjust and strongly built

Wayne

1/2/2021

No problems at all.



by:

This is a heavy duty hitch set up. I have only used it a few times but I know what ever I hook up to. it will get the job done. I have towed a full size suv and a large heavy duty trailer with no problems. This hitch should give a life time of service and then some. If your looking for a heavy duty hitch set up. This is the one you want. Only thing negative is it needs to be able to accommodate a1 7/8” ball. Other than that it’s perfect.
Thanks etrailer for having outstanding products like this to offer your customers.

Chuck D.

1/12/2021

Still looks good and no issues. Does what it was made for. You won’t go wrong with this hitch.



by:

Very pleased with the product quality. The hitch must have been updated since the video and still images were taken. The manual “anti-rattle” design is gone. Replaced by a rubber plug, which I can only assume will work just as well (?). Shipping time was minimal, etrailer has always delivered well.

    We have just what you need. For your Curt Adjustable 2-Ball Mount - 2-1/2" Hitch - 6" Drop, 5-1/4" Rise - 20K # C45902 you will need the Curt Lock Set for Adjustable Channel-Style Mounts # C23556 which was made specifically for this ball mount and will be plenty stable at 20000lbs.

  • Recommended Adjustable Ball Mount for 2-1/2 Inch Receiver and 15,000 lb Trailer
    Based on your question, I assume you have the 2-1/2 inch trailer hitch receiver. There are many options available to assist with your desired towing weight, but there is one that I recommend above the others for ease of use and function at that capacity. I recommend the Curt Adjustable 2-Ball Mount # C45902. This ball mount accommodates up to a 5-1/4 inch rise or up to a 6 inch drop. It adjusts in 1 inch increments and has both a 2 inch and 2-5/16 inch ball. To secure your investment,...

From the furthest hole center to ball center this is 16" length. That is 2-3/4" further than the Curt Rebellion XD Shock Absorbing Adjustable Ball Mount # C57UR and 4-5/8" further than the Curt Adjustable 2-Ball Mount # C45902 that you currently have.

  • Adjustable Ball Mount for 2-1/2 Inch Hitches made in the USA
    Curt trailer hitches are manufactured in the USA but not the supplemental parts like ball mount # C45902. For one that is made in the USA and is similar I recommend # BWTS20037B. But it maxes out at 18K with the 2-5/16 inch ball. The Curt model # C45902 is the only option we have in an adjustable ball mount for 2-1/2 inch hitches that can reach 20K. For a few dollars more you can get the tri-ball model # BWTS20048B. I have linked a video of it for you.

  • Will Curt Adjustable Ball Mount C45902 Fit a 2005 Ford F-350 with Factory 2-1/2 Inch Trailer Hitch
    The Ford 2-1/2 inch trailer hitch on your 2005 F-350 does have a different corner radius then what 2-1/2 inch accessories have so there have been some fit issues. But the Curt products such as adjustable ball mount # C45902 didn't seem to be a problem. In the event that it does have a hard time easily fitting you can sand away some of the powder coat on the ball mount shank and it will fit better.

  • Is Locking Pin Kit for Curt Ball Mounts C45902 and C45900 The Same
    The channel dimensions are the same between the part # C45900 and # C45902 so the locking pins that fit one would also fit the other. For that you would be referring to part # C23556.

  • How To Add a Pintle Hook to the Curt Adjustable 2-Ball Mount
    In order to add a pintle hook to the Curt Adjustable 2-Ball Mount part # C45902 that you have now all you will need to obtain is the Curt Pintle Hook with 2-5/16" Hitch Ball part # C45922. I would also recommend you use the Curt Lock Set for Adjustable Channel-Style Mounts part # C23556 on this setup as it will be a bit more valuable than the standard hitch ball. The Curt Pintle Hook with 2-5/16" Hitch Ball part # C45922 is not offered without the hitch ball attached.

    The weight of the Flash Solid Steel HD Adjustable 2-Ball Mount # FA49-00-5625 that you referenced is 37 lbs, and the weight of the Curt # C45902 is 36 lbs. So in that regard they are essentially the same. They really are quite a bit alike in most ways. Same capacity at 20,000 lbs, both fit 2-1/2 inch hitches, both can do same amount of drop at 6 inches, both are highly reviewed by our customers, and both have very similar prices. I'd say the edge goes to the Curt though since it has two...

One possible solution for you is the Fastway E Series HD Adjustable 18K Ball Mount # FA42-00-2625. A nice feature about the Fastway ball mount is the corrosion resistant aluminum construction.

This ball mount is made from durable heavy-duty steel and has an anti-rattle design to help reduce towing noise.

  • Is there a Ball Mount Larger than a Class V 2-1/2 Inch
    If your hitch receiver opening is larger than 2-1/2 inches then the next step up is a 3 inch if you are talking about physical size and not capacity. The 3 inch ball mount you need is # 40701 if this is the case. The hitch ball to fit is # C40085. This is not a common size though so I do recommend verifying the size of the receiver opening on the hitch. I have also included a link to our ball mount main page.

  • Why Do Rear Tires on Tandem Horse Trailer Run Hotter Than Those on Front Axle
    If the tires on the rear axle of your tandem axle horse trailer are running hotter than those on the front axle, this could be due to several possible causes. One of these causes you mentioned; the trailer not being level when hitched. If the trailer rides nose-high this tends to place more of the trailer's load onto the rear axle. This could easily cause those rear tires to run hotter. All trailers tow best when they are level so if you need to switch ball mounts you can choose one with...
